Abstract: Data characterizing a mother video feed acquired by an endoscopic video capture device can be received. The mother video feed can be for characterizing an operative field within a patient. One or more predefined markers can be identified within the mother video feed. Each of the one or more predefined markers can be associated with a surgical instrument in the operative field. Using the data characterizing the mother video feed, a daughter video feed comprising a sub-portion of the mother video feed can be generated. At least one of a location of the daughter video feed within the mother video feed and a zoom of the daughter video feed can be based on the identified one or more predefined markers. The daughter video feed can be provided. Related apparatus, systems, techniques, and articles are also described.
